From 245d87e93de354f43fcf96d524f50720f7192da4 Mon Sep 17 00:00:00 2001 From: Werner Almesberger Date: Thu, 12 Aug 2010 15:50:38 -0300 Subject: [PATCH] Updated the LED. - BOOKSHELF: added LTST-C190KRKT data sheet - usb.sch: changed R1 to 68 Ohm. C8051F326 VOH at -10 mA is typ. VIO-0.8 V = 2.5 V, the LTST-C190KRKT has Vf at 10 mA typ. ~1.8 V (fig. 2), so we need to burn about 0.7 V. - usb.sch: set the value of VR1, VR2, VR3 (add more details later) --- BOOKSHELF | 5 ++++- usb.sch | 48 ++++++++++++++++++++++++------------------------ 2 files changed, 28 insertions(+), 25 deletions(-) diff --git a/BOOKSHELF b/BOOKSHELF index 10fca8b..0475ab9 100644 --- a/BOOKSHELF +++ b/BOOKSHELF @@ -57,4 +57,7 @@ D: http://www.ndk.com/images/products/catalog/c_NX3225SA-STD-CSR-3_e.pdf #D: http://media.digikey.com/pdf/Data Sheets/NDK PDFs/NX3225SA.pdf?cshift_ck=null&client_id=5042&cshift_ck=null&client_id=5042 # - +# Lite-On 0603 LED, super red +N: ltst-c190krkt +A: led +D: http://optoelectronics.liteon.com/en-us/api/DwonloadFileHandler.ashx?txtSpecNo=DS-22-99-0151&txtPartNo=LTST-C190KRKT diff --git a/usb.sch b/usb.sch index 4317739..35f7569 100644 --- a/usb.sch +++ b/usb.sch @@ -1,4 +1,4 @@ -EESchema Schematic File Version 2 date Thu Aug 12 15:15:06 2010 +EESchema Schematic File Version 2 date Thu Aug 12 15:50:03 2010 LIBS:power LIBS:device LIBS:conn @@ -24,9 +24,9 @@ $EndDescr Wire Wire Line 4750 3450 4750 4500 Wire Wire Line - 5250 1800 5250 1600 + 5050 1800 5050 1600 Wire Wire Line - 5250 1600 5450 1600 + 5050 1600 5350 1600 Wire Wire Line 6550 1600 6750 1600 Wire Wire Line @@ -50,7 +50,7 @@ Wire Wire Line Wire Wire Line 6900 6150 6900 4600 Wire Wire Line - 6750 4800 5600 4800 + 5600 4800 6750 4800 Connection ~ 5600 3650 Wire Wire Line 5600 4800 5600 3650 @@ -64,9 +64,9 @@ Wire Wire Line Wire Wire Line 5150 4900 5150 5100 Wire Wire Line - 5800 3350 5150 3350 + 5150 3350 5800 3350 Wire Wire Line - 5150 3350 5150 4500 + 5150 4500 5150 3350 Wire Wire Line 2350 3350 2550 3350 Connection ~ 1000 3050 @@ -75,12 +75,12 @@ Wire Wire Line Wire Wire Line 1000 3500 1200 3500 Wire Wire Line - 1200 2900 1000 2900 + 1000 2900 1200 2900 Wire Wire Line 1000 3350 1200 3350 Connection ~ 1000 3350 Wire Wire Line - 1000 2900 1000 3700 + 1000 3700 1000 2900 Connection ~ 1000 3500 Wire Wire Line 2350 3500 2550 3500 @@ -97,9 +97,9 @@ Wire Wire Line 3100 4050 3100 3200 Connection ~ 3100 3200 Wire Wire Line - 2350 2900 3700 2900 + 3700 2900 2350 2900 Wire Wire Line - 3700 2900 3700 4050 + 3700 4050 3700 2900 Wire Wire Line 3400 4550 3400 4750 Wire Wire Line @@ -136,7 +136,7 @@ Wire Wire Line Wire Wire Line 7200 5200 9800 5200 Wire Wire Line - 6050 1600 5850 1600 + 6050 1600 5750 1600 Wire Wire Line 5600 2550 5600 2750 Wire Wire Line @@ -192,10 +192,10 @@ $EndComp $Comp L GND #PWR09 U 1 1 4C6408AD -P 5250 1800 -F 0 "#PWR09" H 5250 1800 30 0001 C CNN -F 1 "GND" H 5250 1730 30 0001 C CNN - 1 5250 1800 +P 5050 1800 +F 0 "#PWR09" H 5050 1800 30 0001 C CNN +F 1 "GND" H 5050 1730 30 0001 C CNN + 1 5050 1800 1 0 0 -1 $EndComp $Comp @@ -280,7 +280,7 @@ L VR VR3 U 1 1 4C64034D P 3700 4300 F 0 "VR3" V 3780 4300 50 0000 C CNN -F 1 "VR" V 3700 4300 50 0000 C CNN +F 1 "5V6" V 3700 4300 50 0000 C CNN F 2 "0603" H 3700 4300 60 0001 C CNN 1 3700 4300 -1 0 0 -1 @@ -290,7 +290,7 @@ L VR VR2 U 1 1 4C640343 P 3400 4300 F 0 "VR2" V 3480 4300 50 0000 C CNN -F 1 "VR" V 3400 4300 50 0000 C CNN +F 1 "5V6" V 3400 4300 50 0000 C CNN F 2 "0603" H 3400 4300 60 0001 C CNN 1 3400 4300 -1 0 0 -1 @@ -300,7 +300,7 @@ L VR VR1 U 1 1 4C6402FB P 3100 4300 F 0 "VR1" V 3180 4300 50 0000 C CNN -F 1 "VR" V 3100 4300 50 0000 C CNN +F 1 "5V6" V 3100 4300 50 0000 C CNN F 2 "0603" H 3100 4300 60 0001 C CNN 1 3100 4300 -1 0 0 -1 @@ -310,7 +310,7 @@ L R R1 U 1 1 4C6402F2 P 6300 1600 F 0 "R1" V 6380 1600 50 0000 C CNN -F 1 "100" V 6300 1600 50 0000 C CNN +F 1 "68" V 6300 1600 50 0000 C CNN F 2 "0603" H 6300 1600 60 0001 C CNN 1 6300 1600 0 1 -1 0 @@ -318,11 +318,11 @@ $EndComp $Comp L LED D1 U 1 1 4C6402EE -P 5650 1600 -F 0 "D1" H 5650 1700 50 0000 C CNN -F 1 "LED" H 5650 1500 50 0000 C CNN -F 2 "0603" H 5650 1600 60 0001 C CNN - 1 5650 1600 +P 5550 1600 +F 0 "D1" H 5550 1700 50 0000 C CNN +F 1 "LTST-C190KTKR" H 5550 1500 50 0000 C CNN +F 2 "0603" H 5550 1600 60 0001 C CNN + 1 5550 1600 -1 0 0 -1 $EndComp NoConn ~ 7350 1800
